Aliens Invade South London

New Addington residents were surprised to see what seemed to be the aftermath of a meteor storm when 22 large boulders appeared on the high street earlier this month.

In fact, it's a scheme to deter illegal parking, from London mayor Boris Johnson's Outer London Fund. Local opinion is divided — some residents call the boulders an 'eyesore' and liken them to an alien invasion, while traders say they will stop dangerous parking.

We think they look hilariously out of place, though concerns about people hitting their heads on them after falling over on ice, or that they're disrespectful to the local funeral parlour are perhaps over-enthusiastic.
